Introduction
This manual provides essential information for the safe and effective use of your POWERBLOCK Personal Trainer Set adjustable dumbbells. Designed for versatility and space-saving, this system replaces multiple pairs of traditional dumbbells, offering a weight range from 5 to 50 pounds per hand in 2.5-pound increments. Please read this manual thoroughly before using the equipment.
Key Features
- Adjustable weight from 5 to 50 pounds per dumbbell.
- Weight increments of 2.5 pounds for precise training.
- Compact design replaces 20 pairs of dumbbells, saving space.
- Easy weight selection using a magnetic selector pin.
- Padded handle for enhanced grip and wrist protection.
- Compatible with the Elite/Pro weight stand (sold separately).
Setup
Your POWERBLOCK Personal Trainer Set arrives in two boxes, with each dumbbell ready for use. No complex assembly is required. Ensure both dumbbells are placed on a stable, flat surface or a compatible weight stand before initial use.
Weight Adjustment
- Locate the colored selector pin on the side of the dumbbell.
- To change the weight, pull the selector pin out completely.
- Slide the handle assembly into the desired weight slot, indicated by color-coded labels on the side of the handle. Each color corresponds to a specific weight.
- Ensure the selector pin is fully inserted through the chosen weight plates and handle for secure engagement.
For fine-tuning in 2.5-pound increments, the handle contains two removable adder weights. To adjust these:
- Remove the handle assembly from the main weight stack.
- Locate the small, cylindrical adder weights inside the handle.
- Carefully remove or insert these adder weights as needed to achieve the desired 2.5-pound increment.
- Reinsert the handle assembly into the main weight stack, ensuring the selector pin is securely engaged.

Maintenance
Proper maintenance ensures the longevity and safe operation of your POWERBLOCK dumbbells.
- Cleaning: Wipe down the dumbbells with a damp cloth after each use to remove sweat and dirt. Avoid abrasive cleaners or solvents that could damage the finish.
- Inspection: Regularly inspect the selector pins, handle, and weight plates for any signs of wear, damage, or loose components. Ensure the pins slide smoothly and lock securely.
- Storage: Store the dumbbells in a dry environment, preferably on a dedicated stand, to prevent rust and damage.
Troubleshooting
If you encounter any issues with your POWERBLOCK Personal Trainer Set, please refer to the following common solutions:
- Difficulty adjusting weight: Ensure the selector pin is fully pulled out before attempting to slide the handle. Check for any obstructions between the weight plates.
- Dumbbell feels unstable: Verify that the selector pin is fully inserted and locked into the chosen weight plates. The handle should not wobble excessively.
- Rust formation: This can occur in humid environments. Regular cleaning and storage in a dry area can prevent this. Minor surface rust typically does not affect performance but should be monitored.
